Abstract

The invention concerns an electronic time-piece having a barometric indicator, indicating, for example, barometric trends. The time-piece comprises, in addition to the reference oscillator for determining the time, a measurement oscillator associated with a transducer exposed to the ambient air. A counter measures the variations of the frequency of the measurement oscillator due to the fluctuations of atmospheric pressure, and an electronic circuit controls, from predetermined detection thresholds, the indication of barometric trend on the display device of the time-piece.
